On bootup, with MTD debugging and JFFS2 debugging on,  the 2.2.18 kernel
give me this:

But I don't see any JFFS2 output (formatting the blocks...etc...) on the
2.4.20 kernel I'm trying to get running:

Warning: unable to open an initial console.

Is it possible that the JFFS2 MTD partition isn't being mounted, and
therefore that is why the console, and INIT aren't starting?
